Question

The value of $\left(-5x^{2}y\right)\times \left(-\frac{2}{3}x{y}^{2}z\right)\times \left(\frac{8}{15}xy{z}^2\right)\times \left(-\frac{1}{4}z\right)$ is

Answer 1

now we can also write

$=>[-5\times \frac{-2}{3}\times \frac{8}{15}\times \frac{-1}{4}]\times x^4{y}^4{z}^4$

$=>\frac{-80}{180}\times x^4{y}^4{z}^4$

$=>\frac{-4x^4{y}^4{z}^4}{9}$
